I would think any lens with a metal barrel and components, with no cemented
optical elements, should be as resistant to thermal stress as anything.
Just a theory.
Wouldn't it be irrelevant with "cold" light enlargers anyway? I've never
used one, but it seems they'd be much cooler than the old enlargers I used,
which didn't get that hot at the lens mount anyway.

Hmm, I once heard that photograpic-lenses should used very carefully for
enlarging
purposes, because they are generally (!) not designed to withstand the
thermal long-time
stress, when used as an enlarging lens.
